  • 63K template toolkit

  • 43K configuration system

  • 17K Perl scripts

  • 25K web framework

Infrastructure

• Hosted on DigitalOcean VPS

• Ubuntu 22.10 (scheduled for upgrade)

• Dev / Stage / Production environments

• python services are Dockerized

• Perl system is not containerized

• Partial CI/CD automation (python only)

• Infrastructure managed by current Senior Developer

• Automated database backups + monthly restore testing

• No replication currently

• Downtime tolerance: up to 8 hours (business continuity procedures exist)

---

Migration Status & Goal

We are executing a phased migration from Perl to python.

• ~20% already migrated

• Target: >80% migrated within 12 months

• End goal: full replacement of legacy Perl system

Current modernization streams:

1. Migrate email & WhatsApp handling to AI-driven solution

2. Rebuild core order management functionality in python (FastAPI)

3. Develop new UI for drivers and hostesses

4. Gradually decouple monolith into modular services

This is a controlled, staged production migration.

Team Structure

• 1 senior developer (20 years on system)

• 1 QA

• No dedicated undefined

• Requirements defined by business + management + senior dev

• Production incidents handled by senior dev

• Very stable production system (minimal incidents in last 12 months)

This role will significantly strengthen and eventually take ownership of the modernization effort.
